To ctZZ whom it may concern:

Be it known that I, HENRY 0. SMITH, a citizen 0f the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented anew and usef ul Improvement in Window-Frames,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a metallic windowframe made of sheet metal and having the construction hereinafter specified.

In the drawings, Figure 1 is aview in elevation of the window and sash frames. Fig. 2 is a vertical section, enlarged, of such portions of the frames as are necessary to show their construction and upon the dotted line 2 2 of Fig. 1. Fig. 3 is a view in horizontal section upon the line 3 3 of Fig. 2. Fig. 4 is a horizontal section, enlarged, of a mullion upon the dotted line 1 4 of Fig. 1. Fig. 5 is a view enlarged, partly in vertical section and partly in side elevation, to show especially the construction of the side-bead strips and the manner of placing the windowsashes in the frame. Fig. 6 is a View in elevation of these parts to further illustrate this feature. Fig. 7 is a view-in horizontal section upon the dotted line 7 7 of Fig. 5. Fig. 8 is a View in horizontal section upon the dotted line 8 8 of Fig. 5. Fig. 9 is a view in perspective to represent the final shape of the various parts forming one side of the frame, but separated from each other. Figs. 10, 11, 12, and 13 are perspective views of portions of the sash-frame, to which reference will hereinafter be made.

I will first describethe construction of the window-frame. It will be understood that it and the sash are especially designed for use in fireproof buildings and because of their fireproof construction.

Ordinarily the window-frame as a Whole is built into the brick or fireproof wall as the wall is laid. In the drawings, A, Fig. 3, represents a conventional fireproof wall, and the recess which is formed about a portion of the window-frame as the wall is laid is lettered B. The complete window-frame comprises the vertical side portions and the horizontal top and bottom connections. Each of the side portions of the frame is made of plates of fiat sheet metal, which are in their completed and united form shown in Fig. 3. They are also shown dissociated in Fig. 9, that their shape and construction may be better understood and followed. Each side portion consists of two weight-holding box-like sections 0 0 arranged side by side and each made of a single plate, shaped as hereinafter specified, which forms the side walls, outer flanges and facing, and the open back of the section, and these sections are combined together by a back plate common to both and by abeadforming plate in two parts, also common to both.

Referring to Figs. 3 and 9, the plate which forms the box-like sections 0 of the frame is shaped to form an inner edge 0, where it is bent upon itself to form one member of a locking-joint, the other of which members is formed upon the edge of the back plate above referred to. From the locking-joint it extends to the corner 0 furnishing one wall of the box. From the corner 0 it extends at a right angle to the corner 0 where it is again bent, preferably at a right angle, and extends to the corner a, where again it is bent at a right angle and extends backward to the corner 0 where it is bent inward at a right angle and extending to itsinner edge 0 forms the inner wall of the box-section. The portion bounded by the angles 0 c 0 forms a flange to rest against the building-wall surrounding the window-space, and the part between the angles 0 0 forms an outer facing, which is covered by a bead-forming strip, as hereinafter specified. The section 0 of the frame is of a similar shape. It extends from the inner corner 0 where its edge is bent to form a member of a locking-joint, to the point 0, where it is bent at a right angle, thence to the point 0 where it is again bent at a right angle, thence to the inwardly curved corner o thence to the right angle e thence outward to the right angle 0, thence to the right angle 0, thence backward to'the right angle e thence to the right angle c, and thence inward to its edge 0". The portions between the angles from c to 0 form two flanges, one of which rests against the wall of the windowrecess and the other of which projects at a right angle to the first to form the outer ledge or bead of the outer sash guideway or runway of the frameor aportion of it. These two sections 0 c are combined together at the back by a back plate D, the edges d d of which are bent at an angle to form sections to interlock with the locking-joints of the.

The sections cc are combined on their outer surfaces by the bead-forming plate E, which; lismade in two sections-namely, the upper.

section E and the lowerseetion E (See Figs.

5 and 6.) Each section of the plate is formed along one edge e toa shape to engage andcon-i tain the outer flange-forming section of the frame.

This shape is preferably rectangular, I

open on its in nerside, and of a size to fit over the flange-forming section of the frame.

.Fromthence itlextends parallel with the outer 5 face of the section 0 to its angle c where it is bent outwardand returned (see Figs. 5 and S) to form the central bead e, which separates longitudinally the two window-runways ofthe frame. The bead-formingplate thence extends parallel with the face of the section 0 to the angle 6 where it is bent outward at a right angle e and thence extended to the curved edge 6 which is adapted to come into contact with the face of the section a near its angle c ,.thus forming the inner flange to the inner sash-runway.

The central bead-forming section 6 of the ahead-forming plate and the inner walls of the sections 0 0 near the angles 0 c may hold between them a flat plate Fto stiffen the bead and frame, and in use I prefer to .unite it to the'bead-formingplate, as representedin Fig. '8, before it is applied to the faces of the boxsections. The bead-forming plate is made in the two parts E E in order that the windowsashes mayibe readily placed in the frame. This is done by first putting in place the upper sections of the bead-forming plate and by then placing in the outer runway thereof the outer sash and in the inner runway thereof the inner sash, both sashes being introduced into the runways of the upperpart E of the beadllJlflJtG from below. After the innersash has been placed in position the lower sections of the bead-forming plate are put into place against thesides of the frame,.and the meeting-points of the two sections of the beadforming plates may be so constructed that each upper one shall lap slightly upon the lower one, and each lower section may also be secured inplace by a screw passing through an ear into a wood filling-piece of the sill.

It will be seen from what I have said that. eachside of the window-frame is formed of a 1 structure made of five principle plates connected to form a section G, having inwardextend ingxangular stiffening-joints at its inner corners and midway between the same lateral shoulders or extensions G G a permanent outer flange G a central spacingbead b, and a permanent inner flange G, and that the outer flange, central bead, and inner flange establish the two guideways G G6 for the window-sashes H H.

The side sections of the frame are joined at their upper ends, preferably by miter-joints withthetop section I. (See Fig. 2.) This section comprises a cross filling-piece, *i of wood, inclosed by a metal covering-plate, the edges t" of which lap upon a plate i 'upon the upper face of the piece and is fashioned to provide the outer face 2 the horizontal top flange 1;, which .isa continuation of the flange G the horizontal central :bead i which isa continuation of the bead e, the face i to the :top of the 'uppensash guideway, the face '17 to the top of thelower-sash.guideway, and the inner face i A metallic molding i lmay be .applied to the face 2' as represented in Fig. The lower corners of the side sections of A1110 frame are united, preferably, by miter-joints tothe metal housiugJ, inclosing the wooden filling-piece or sill j. This housing is shaped to entirely cover the inner sidej of the piece 7' to form the sillj the outer face or 'flangej of the sill, the inclined surface 3' extending from the sill outward, and the :outer face andithe ed gesj of this covering-platearebent upon a flat plate 3' which covers the under surface of "the wooden sill. (See Fig. 2.)

It will be understood that thesectionsc c of the frameare hollowrand form the windowweight-holding cavities and are provided with the openings 0 c ,.'(see Fig. 5,)th rough which the weights are entered into the cavities, and which openings are covered by the lower sections of the bead-forming plates.

The .two window-sashes H :11 are made in substantially the same way, and "the description of one will answer for both.

The frame of the sashes is hollow and made of sheet-metal plates fashioned as hereinafter described. The sides 71 of the frame are made of the plates it he. The plate h is formed at the center of its length with a vertical pocket for holding the side edge h of the pane 7L4.

It is further shaped to provide the'innerand outer sides h h of the sash, .theside corners 71 72 and the interlocking sections h" of a joint. The .plate 77 provides the inner face h of the sash and is shapedto form outward angular extensions and interlocking edges, which interlock with the joint-forming'parts of the first-named .plate h. This construction provides the sash-frame with stiffness.

and with pockets the full length of the sash,

in which the sash-cord may be held and play,

thus permitting the cords to be fastened to "the sides of the sash at any desired point.

These side sections of the sash-frame are united to the top and bottom crosssections or bars h h by'miter or other joints, and the upper cross-section h of the lower sash may be made, as represented in Fig. 2, of three plates bent to form the parts h h h, the part 71. having the wall It", the face h the inward extension h and the joint-forming section h and the part 71. having the wall it, the outer face M the inward-returning section 71 and the joint-forming section It. The walls h h are separated from each other by a space equivalent to the thickness of the pane of glass, and the two parts 71 h are not joined until the pane has been slid down between them into the side pockets of the side sections of the sash and the lower pocket of the lower section of the sash-frame, when they are united by the plate h which is of a width to extend to the upper corners of the parts h 71, and to be bent backward upon itself and downward to make 3' oint-forlnin g sections h ,which are combined with the j oint-forining sections 71 71 of the parts h It. (See Fig. 2.)

The lower cross-piece 71 of the sash is made of the two parts 7L2 and h The part 71. has the pocket h for receiving the lower edge of the window-pane. It also forms the sides 7L3) 7L and is united at its lower corners to the bottom part 7& by a stiffening overlapping corner-joint of the character already described.

Instead of a pocket or groove for receiving the glass the sash may be provided with a shoulder, as represented in Fig. 11, against which the glass may be set in any desired way. I

In Fig. 12 I have represented a form of joint which in some instances I prefer to emp y- It will be understood that the invention is for the purpose of providing a fireproof window-casing and window and that the casing and window are used in connection with fireproof surroundings, such as a brick or metal wall, and that it is preferable that the window-glass used should be of the kind known as wire-glass.

The mullions may be made, as represented in Fig. 4t, of two pieces of sheet metal, one of which is fashioned to form the part L and the other of which is fashioned to form the part L, the two parts having a glass-receiving recess between them and portions of the part L lapping upon the part L, as represented in Fig. 4.

The meeting-rails of the sashes may be bent outward at 70 70 to come into contact with each other when closed, as represented in Fig. 2.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States I 1. A metallic window-frame having hollow side-forming sections comprising the parts a, a shaped substantially as described, and the inner combining-plate D uniting the inner edges of the side sections, and the beadforming plate E made in the two parts E, E and united to the side-forming sections, as and for the purposes set forth.

2. A metallic window-frame having hollow side-forming sections comprising the parts 0, c shaped to form the section G, and the flanges G, G G the inner combining-plate D united to the sections a, c substantially as described to lock and stiffen the inner corners thereof, and the bead-plate E formed in two parts E, E each having a central bead and two flanges forming the runways for the window-sashes, one of which flanges is extended to form a molding and the other of which to inclose the flange G and a bead stiffening or reinforcing plate, as and for the purposes set forth.

3. In a metallic Window-frame the combination of the hollow sections a, 0 having in their faces weight-openings, the combiningplate D and the sectional bead-forming plates E, E one of which is adapted to be secured to the sections 0, c in advance of the other, and one of which also covers the said weightopenings, as and for the purposes set forth.
